安装.NET Core 2.0后运行dotnet CLI提示缺失DLL错误求助

Hey Vivek, I’ve dealt with this exact headache on Windows 7 before—let me walk you through the most reliable fixes that got it working for me and other devs:

• Install critical Windows 7 updates first
  .NET Core 2.0 relies on some system components that aren’t included in a vanilla Windows 7 install. You’ll need to grab and install these updates:

  • KB2533623 (adds support for newer cryptographic algorithms)
  • KB2999226 (provides the Universal C Runtime)
    Head to Windows Update to search for these, or download them directly from Microsoft’s update catalog if Windows Update isn’t cooperating.

• Reinstall the .NET Core 2.0 Runtime/SDK
  Sometimes the installation process skips or corrupts DLL files. Uninstall your current .NET Core 2.0 installation via Control Panel > Programs and Features, then download the correct installer (match x86/x64 to your system) from the official archives. Run the installer as an administrator to avoid permission issues during setup.

• Install the required Visual C++ Redistributable
  .NET Core 2.0 depends on the Visual C++ Redistributable for Visual Studio 2015 Update 3. If this isn’t installed on your system, it’ll throw missing DLL errors. Grab the version matching your system architecture and install it—this usually fixes the majority of missing DLL cases.

• Double-check your system PATH
  Make sure the .NET Core installation directory (typically C:\Program Files\dotnet\ for 64-bit, or C:\Program Files (x86)\dotnet\ for 32-bit) is listed in your system’s PATH environment variable. If it’s missing, add it manually, then restart your command prompt to apply the change.

If none of these work, try running a repair on your .NET Core installation (note: the dotnet --repair command was introduced in .NET Core 2.1, so for 2.0 you might need to use the installer’s repair option if it’s available).
